Problems solved by technology

[0003] Usually, a thick layer of scale will be formed on the fins of the plate heat exchanger after being used for a period of time, which seriously affects the heat exchange efficiency of the equipment. The general scale cleaning method is to soak with 30% oxalic acid or a special boiler descaling agent Cleaning, this cleaning method will cause certain damage to the staff and the working environment, so we have studied a physical method to solve the scale cleaning of plate heat exchanger fins by using sunlight exposure and beating fins

Embodiment Construction

[0016] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0017] The application principle of the present invention will be further described below with reference to specific embodiments.

[0018] A method for cleaning scale of plate heat exchanger fins, comprising the following steps:

[0019] a) Place the scaled side of the plate heat exchanger fins on a sunny ground for sunlight;

[0020] b) When the scale on the fins appears dry cracks, lift the fins and beat them on the rubber pad, the scale will fall off by itself, rinse with clean water and then reuse.

[0021] The present invention selects five plate heat exchanger fins and divides them into five groups A, B, C,...

Abstract

The invention relates to a method for cleaning scale on fins of a plate type heat exchanger. The method comprises the following steps: a) placing the sides, with scale, of the fins of the plate type heat exchanger on the ground with sufficient sunlight for sunlight irradiation; and b) when dry cracks occur in the scale on the fins, lifting and beating the fins on a rubber pad till the scale automatically falls off, and washing with clear water, so that the fins can be reused. According to the method, the scale on the fins of the plate type heat exchanger is removed in a sunlight exposure and fin beating mode, so that the descaling rate can reach 90%, workers and the working environment cannot be hurt, materials of the fins of the plate type heat exchanger cannot be corroded or damaged, theservice life of the plate type heat exchanger can be prolonged, and the heat efficiency of the plate type heat exchanger can be improved.

Description

technical field [0001] The invention relates to the technical field of scale removal of plate heat exchangers, in particular to a method for cleaning scale of plate heat exchanger fins. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, wide application and long service life. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, the floor area is one third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90% or more. [0003] Usually, a thick la...
